Arowana health problems. In need of advice.

Aloha everyone!

I'll get straight to the point. My Silver arowana (about 3 inches) has problems swimming as well as maintaining itself... Allow me to explain, the day after i bought 2 arowana's from my lfs about 2 and half weeks ago it was doing fine. Food given to it was hikari cichlid gold along with blood worms once or twice a week. A week after I bought 6 bala sharks about an inch long and quarantined and added a parasite guard. Now I've only added the bala sharks in two days ago and when i came home today my entire fish crew had ich on them. My petricola's had them all over their body, my royal pleco, especially my bala's. Just a few on my arowana BUT!!! Now my arowana isn't maintaining itself. It's head is facing the gravel and his tail is facing upwards towards ceiling. His tail is gone, He is still breathing though. I'm not to sure what the problem is. I'm also in the process of curing the tank. heat & monitoring temps/ aquarium salt as well as Ich-X which was recommended to me by everyone in my lfs. Been doing water changes weekly but now I've just finished it due to ich reproduction. Been watching my water parameters Ph-7.0 Ammonia-0, Nitrites-0...
First time raising an Arowana so i do need tips. I read forums before actually getting one. My other one is doing well (in separate tanks) Just this one i decided to add bala sharks ruined everything
Both Aro's are in 75 gallon tanks. Any additional info that'll help me save my aro will be provided if asked. Don't wanna lose my buddy

Baby aros do best by themselves and should be fed 2 times a day with a varied diet. It doesn't sound like your aro is going to make it. I still feed my 2 foot long aro twice a day. They grow incredibly fast and need a lot of food. Best advice I can offer for your baby aro is get it into a tank by itself with adequate filtration, clean water, and feed much more often. A baby aro needs way more food than what your giving it. Aros are not usually prone to ich, so my guess is aggressive tank mates coupled with lack of nutrition, and likely poor water conditions caused this.

Mahalo's for the information. The aro didn't make it. I think I actually found out the reason why. After going back to my lfs I noticed they had a tank and will not sale the fishes inside them and they happen to be the rest of the bala sharks I bought before. Same exact traits with white spots/ white coating around it's fins/body. I believe my lfs has given me fishes with parasites internally in them( I could be wrong)
Also my Petricola's 2 of them didn't make it as well. they're just covered in ich... Seriously worried about it now. Should i just water change the entire tank and strainer the gravel again? Then continue on doing water changes every other day.

It's a hard lesson to learn. All new fish should be isolated and monitored for at least 6 weeks before adding them to your existing stock. Quarantining new fish is an absolute must.
